The VSSPLL pin should always be grounded even if the PLL is not used.
The VDDPLL pin should not be left floating. It is recommended to
connect the VDDPLL pin to ground if the PLL is not used.
PLL loop filter. Please see
information on how to calculate PLL loop filter elements. Any current
leakage on this pin must be avoided.
Stand-by voltage supply to static RAM. Used to maintain the contents of
RAM with minimal power when the rest of the chip is powered down.
Internal power and ground.
External power and ground, supply to pin drivers.
Operating voltage and ground for the analog-to-digital converter, allows the
supply voltage to the A/D to be bypassed independently.
Reference voltages for the analog-to-digital converter 1
Reference voltages for the analog-to-digital converter 0.
